How to customize live Ubuntu CD?
I wonder that whether there is a way of making my own installed ubuntu a live USB. The reason in fact is that I want to make my ubuntu to be used by anybody. After this guy used my ubuntu I do not want to see his garbage on my ubuntu. I want to see my ubuntu how it was looking before I gave it to him. Therefore, I have assumed that it is the best way of avoiding this problem.
Okay let me clear my point. Lets assume I want to make a internet cafe-like system. Every user will be able to enter via only one user account to linux. However, I do not want them to leave anything behind. Whenever this ubuntu is booted, I want to this system remove their garbage. Why I mentioned the live USB is that I have seen that live usb or cd makes what I want but not exactly because I want to install some apps on it and make some confugration like firewall, permissions.
The problem with using just the guest session is that it does not obey my rules like firewall, my limitation on the apps and so on.
